1 Use a debugger

A debugger is a tool that allows you to inspect and manipulate the state of your program as it runs. You can use a debugger to set breakpoints, step through the code, watch variables, evaluate expressions, and modify values. A debugger can help you isolate the location and the cause of a bug by showing you the exact flow and behavior of your code. Depending on your programming language and environment, you can use different debuggers, such as Chrome DevTools, Visual Studio Code, or PyCharm.

Debuggers are great, you could also use logs or printing to the console as your form of debugging. The key here is patience to go through each step of the code, keeping track of a variable types and changes.

Systematically review recent code changes, replicate the bug, and isolate variables. Utilize debugging tools, analyze error messages, and seek input from team members. Collaborate openly, consider environmental factors, and leverage version control to pinpoint the root cause efficiently.

In debugging, it's not just the 'what', but the 'why' that matters. Take a common scenario like a memory leak in a Node.js application. By adeptly using a debugger, one can trace such an issue to an unmanaged resource in a loop. This discovery isn't just about fixing a bug; it prompts a review of resource management practices. It shows how deep analysis can transform a simple bug fix into a learning opportunity, strengthening the overall resilience of the code.

2 Follow the stack trace

A stack trace is a report that shows the sequence of function calls that led to an error or exception. A stack trace can help you trace the origin and the context of a bug by showing you the line number, the file name, and the function name where the error occurred. You can use a stack trace to narrow down your search and identify the relevant parts of your code. You can also use a stack trace to check the values and types of the arguments and parameters that were passed to each function.

Breakpoints in a stack trace could help to narrow down a list of possible culprits. They will help to control a data flow and have a better understanding of what actually happens without any necessity to alter code.

3 Reproduce the bug

Reproducing the bug means recreating the exact conditions and inputs that caused the bug to appear. Reproducing the bug can help you verify and validate the bug by showing you the expected and the actual output of your code. You can use different methods to reproduce the bug, such as using test cases, sample data, user feedback, or logs. You can also use different tools to reproduce the bug, such as Postman, Selenium, or Cypress.

In bug reproduction within React development, we essentially handle two categories: user-specific and universal bugs. Initially, it's crucial to collect user feedback and understand the context of the issue. If we can replicate the bug in our environment by mimicking the same conditions, it's likely a universal error. These are generally more straightforward to resolve. The challenge arises when we cannot reproduce the bug despite following the same steps. This is where thorough investigation becomes essential. We question each element: Could there be an undefined data point? A failed network request? We explore these potential triggers that leads to the issue But with effective logging, we reduce the guess work and fasten the process

4 Simplify the problem

Simplifying the problem means breaking down the bug into smaller and simpler parts that are easier to understand and solve. Simplifying the problem can help you eliminate irrelevant and unnecessary factors that may interfere with your debugging process. You can use different techniques to simplify the problem, such as commenting out code, using print statements, using dummy data, or using the binary search method.

5 Use the scientific method

The scientific method is a systematic and logical approach to solving problems based on observation, hypothesis, experiment, and conclusion. It can be used to debug code by observing the bug and gathering information about its symptoms, frequency, and impact. Then, formulate a hypothesis about the possible cause and solution of the bug and design an experiment to test it. Analyze the data and draw a conclusion about whether your hypothesis was correct or not. If not, repeat the process until you find the root cause and fix the bug. This method of debugging can help you find the source of a bug by testing your assumptions and validating your results.

6 Seek help

Seeking help means asking for advice or assistance from other developers who may have more experience or knowledge about the bug or the code. Seeking help can help you overcome the challenges and limitations of your own perspective and skills by providing you with new insights, ideas, or solutions. You can seek help from different sources, such as your colleagues, mentors, online forums, or documentation.

Don't be afraid to ask for guidance from your colleagues if you have done everything you can think of what would be the cause of the underlying bug.

Keep those console/network tabs of your browser's developer tools open at all times when developing web apps. If the bug is new from the changes you've made, there's a possibility those will tell you that in detail.

The first tool for productive debugging is good code quality. Design patterns, style guides, unit tests, and principles like SOLID and KISS — all will help to write easy-to-debug code
